Description

【0001】
【発明の属する技術分野】
本発明は、圧縮機等を備えた冷凍ユニットが配設される冷凍機本体の機械室における前後両面に、それぞれ外部から機械室内に空気を吸い込む吸込口と機械室内で熱交換された後の空気を機械室の外部に排出する吹出口とを形成した冷凍装置に関し、特に、吹出口から排出された熱交換後の空気が吸込口から機械室内に吸い込まれることを防止しつつ、冷凍機本体の底部下方における設置面の掃除を容易に行うことが可能な冷凍装置に関するものである。
【0002】
【従来の技術】
従来より、冷凍装置としては、種々のものが提案されている。例えば、特許文献1には、断熱箱体の機械室内でユニットベースに凝縮器等からなる冷凍ユニットを配設し、かかる機械室の前面に外気吸込口を形成するとともに後部に熱交換後の空気を吹き出す吹出口を形成し、また、機械室の吸込口下方に熱交換後の空気が吸込口から吸い込まれることを防止するガードを設けた冷凍装置が記載されている。
ここに、前記のような冷凍装置は、その設置スペースの有効利用を図るべく、特許文献1の図4に示されているように、部屋の隅部で壁に近接して配置される場合が多い。かかる場合、機械室の後部に形成された吹出口から吹き出された熱交換後の空気は、部屋の壁に衝突した後方向を変え、台脚を介して断熱箱体の底面と設置面との間に形成される間隙を前方側まで移動し、機械室前面の吸込口から機械室内に吸い込まれてしまう虞がある。このとき、機械室の吸込口下方に設けられたガードは、前記のように移動する熱交換後の空気の流れを遮断して、吸込口に吸い込まれることを防止するものである。
【0003】
【特許文献1】
特開平9−119766号公報(第2頁、第3頁、図1乃至図4)
【発明が解決しようとする課題】
前記した冷凍装置では、機械室の吸込口下方にガードを設けていることから、機械室後部の吹出口から吹き出された熱交換後の空気が機械室前面の吸込口から機械室内に吸い込まれてしまうことを防止できるものではあるが、ガードは機械室の下部に不動状態で固定されている。
ここに、前記冷凍装置では、断熱箱体の底部に設けられた台脚を介して断熱箱体の底面と設置面との間には間隙が形成されており、特許文献1の図4に示すように、部屋の隅部にて長期に設置しておくと、断熱箱体の底面と設置面との間隙に埃、ゴミ、虫の死骸等の各種の塵埃が溜まってしまう。このように、断熱箱体の底面と設置面との間隙に各種の塵埃が溜まった場合、これを掃除する必要がある。
【0004】
しかしながら、前記したガードは、機械室の下部に不動状態で固定されているので、断熱箱体の底面と設置面との間隙に溜まった各種の塵埃を掃除する場合、間隙にモップ等の掃除具を入れる箇所が限られてしまうと同時に、塵埃を掃き出す箇所も限られてしまう。特に、ガードが固定された機械室の前面側からはモップ等の掃除具を入れること、及び、塵埃を機械室の前面側から掃き出すことは極めて困難なものである。
これより、断熱箱体の底面と設置面との間隙に溜まった塵埃の掃除を短時間で効率良く行うことはできないという問題がある。
【0005】
本発明は前記した従来における問題点を解消するためになされたものであり、吹出口から排出された熱交換後の空気が吸込口から機械室内に吸い込まれることを防止しつつ、冷凍機本体の底部下方における設置面の掃除を容易に行うことが可能な冷凍装置を提供することを目的とする。
【0006】
【課題を解決するための手段】
前記目的を達成するために請求項1に係る冷凍装置は、冷凍ユニットが配設される機械室を有する冷凍機本体と、前記機械室の前面に形成され、外側から空気を機械室内に吸い込む吸込口と、前記機械室の後面又は底面に形成され、機械室内にて熱交換された空気を機械室の外部に排出する吹出口とを有する冷凍装置において、前記冷凍機本体の底部に設けられ、その底部を設置面から一定距離離間させる脚部材と、前記吸込口の下方で機械室の下部に設けられ、前記吹出口から排出されるとともに前記冷凍機本体の底部と設置面との間を移動する熱交換後の空気が吸込口から機械室内に吸い込まれることを防止するショートサイクル防止板を備え、前記ショートサイクル防止板は、機械室の下部に対して回動可能に取り付けられていることを特徴とする。
【0007】
請求項1に係る冷凍装置では、部屋の隅部にて壁と近接して設置された場合、機械室の吹出口から排出された熱交換後の空気が、部屋の壁に衝突した後方向を変えて、脚部材を介して一定距離離間される冷凍機本体の底部と設置面との間に形成される間隙を機械室の前面側まで移動しても、かかる熱交換後の空気は、ショートサイクル防止板を介して遮断されるので、機械室の前面に形成された吸込口から機械室内に吸い込まれることを確実に防止することが可能となる。
また、ショートサイクル防止板は、機械室の下部に対して回動可能に取り付けられているので、冷凍機本体の底面と設置面との間隙に溜まった各種の塵埃を掃除すべく間隙にモップ等の掃除具を入れた際に、掃除具がショートサイクル防止板に当たっても、ショートサイクル防止板は自在に回動することができる。これより、冷凍機本体の底面と設置面との間隙にモップ等の掃除具を入れる箇所が限定されてしまうことはなく、また、塵埃を掃き出す箇所も限定されることはない。特に、ショートサイクル防止板が取り付けられた機械室の前面側から掃除具を入れることが可能となり、また、塵埃を機械室の前面側から掃き出すことも可能となる。従って、冷凍機本体の底面と設置面との間隙に溜まった塵埃の掃除を短時間で効率良く行うことができる。
【0008】
【発明の実施の形態】
以下、本発明に係る冷凍装置について、本発明を製氷機につき具体化した一実施形態に基づき図面を参照しつつ説明する。
先ず、本実施形態に係る製氷機の概略構成について図1及び図2に基づき説明する。ここに、図1は製氷機の上部を省略して示す模式側面図、図2は機械室における冷凍ユニットのレイアウトを模式的に示す平面図である。
【0009】
図1において、本実施形態に係る製氷機1は、製氷機本体2を有しており、かかる製氷機本体2には、その上側に貯氷室3が設けられるとともに、下側に機械室4が設けられている。貯氷室3の内部には、冷凍サイクルの一部を構成する製氷ユニット(図示せず)が配設されており、製氷ユニットで製氷された氷は、貯氷室3に貯氷される。貯氷室3の前面側(図1中左側)には、貯氷室3に貯氷された氷を取り出すための扉5が開閉可能に取り付けられている。
また、機械室4の内部には、図2に示すように、機械室4の底部を構成するベース板6上に、前記貯氷室3内の製氷ユニットと共に冷凍ユニットを構成する各種の装置が配設されている。ベース板6上には、図2に示すように、仕切板7及び8が配設されており、また、仕切板8の端部(図2中側端部)に連続するように、フロントパネル9(後述する)側まで延びる仕切板10が設けられている。
【0010】
ここに、図2において、各仕切板7、8、10を介して仕切られる右下側部分は吸気側を構成し、また、各仕切板7、8、10を介して仕切られる左上側部分は排気側を構成する。吸気側には、フロントパネル9に近接して電装箱11が配置されており、また、仕切板7と8の間で、吸気側と排気側の境界には、凝縮器12及び冷却用送風機13が配置されている。更に、排気側には、圧縮機14が配置されている。
また、機械室4において、フロントパネル9と対向する側には、リアパネル15が取り付けられている。尚、フロントパネル9には、後述するように、製氷機1の外側から空気を機械室4内に吸い込む吸込口が形成されており、また、リアパネル15には、後述するように、機械室4内で熱交換された後の空気を機械室4の外部に排出する吹出口が形成されている。
【0011】
製氷機本体2に設けられた機械室4の底部における四隅には、アジャスタ脚16が設けられている。各アジャスタ脚16は、図1に示すように、製氷機1が設置される設置面17と機械室4の底面18とを一定距離離間させることにより、設置面17と底面18との間に間隙19を形成する。
なお、前記製氷機1は、その設置スペースの有効利用を図るべく、図1に示すように設置部屋の壁面20に近接して設置されているものとする。
また、製氷機1の前面側において、フロントパネル9の下方で機械室4の下部には、図1に示すように、ショートサイクル防止板21がヒンジ22を介して回動可能に取り付けられている。
【0012】
ここで、フロントパネル9及びリアパネル15の構成、並びに、ショートサイクル防止板21の取付構造について、図3乃至図5に基づき説明する。図3はフロントパネル側から見て拡大して示す機械室の説明図、図4はショートサイクル防止板の取付構造を拡大して模式的に示す説明図、図5はリアパネル側から見て拡大して示す機械室の説明図である。
先ず、フロントパネル9とリアパネル15の構成について説明する。図3に示すように、機械室4の前面側に取り付けられたフロントパネル9には、外部から機械室4内に空気を吸い込む吸込口23が縦方向に4列に形成されており、また、機械室4内にて熱交換された後の空気を機械室4の前面側外部に排出する吹出口24が縦方向に2列に形成されている。尚、図3において、右側から3列目と4列目の吸込口23との間にはスペースが設けられているが、これは、3列目の吸込口23と4列目の吸込口23との間には、図2に示すように、電装箱11が配置されていることから、電装箱11から発生する熱を電装箱11の両側から効率的に排熱するためである。
また、機械室4の後面に取り付けられたリアパネル15には、図5に示すように、機械室4内にて熱交換された空気を機械室4の後面側外部に排出する吹出口25が横方向に4列に形成されている。
【0013】
続いて、ショートサイクル防止板21の取付構造について、図3及び図4に基づき説明する。図3及び図4において、機械室4の底部を構成するベース板6の前端面には、2つのヒンジ22を介してショートサイクル防止板21が回動可能に取り付けられている。即ち、各ヒンジ22の上側部分は、ネジ26を介してベース板6の前端面に固定されており、また、各ヒンジ22の下側部分は、ショートサイクル防止板21の上端縁にネジ26を介して固定されている。これにより、ショートサイクル防止板21は、通常状態で、図4の実線で示す位置に停止しているが、前方方向(図4中左方向)への力が作用すると、矢印Y1方向へ2点鎖線で示す位置まで回動し、また、後方方向(図4中右方向)への力が作用すると、矢印Y2方向へ2点鎖線で示す位置まで回動することが可能である。このように、ショートサイクル防止板21は、略180度の範囲で前後方向へ回動可能に構成されている。
【0014】
ここに、ショートサイクル防止板21の右端は、図3に示すように、右側のアジャスタ脚16から距離L1だけ離間するように取り付けられている。これは、前記のようにショートサイクル防止板21が前後方向に回動する際に、アジャスタ脚16に接触することを防止するためである。
また、ショートサイクル防止板21の左端は、図3に示すように、フロントパネル9に形成された3列目の吸込口23の左端から距離L2だけ離間するように取り付けられている。これは、後述するように、リアパネル15に形成された吹出口24から排出された熱交換後の空気が、間隙19を通って機械室4の前面側まで移動してきた際に、3列目の吸込口23から吸い込まれ難くするためである。
【0015】
前記のように構成された製氷機1が作動された際におけるショートサイクル防止板21の作用について説明する。このとき、ショートサイクル防止板21は、図4にて実線で示す位置に停止しており、前後方向に回動されることはない。
機械室4内の冷凍ユニットが駆動されることに基づき、冷却用送風機13が回転駆動され、フロントパネル9の各吸込口23を介して外部から空気が機械室4内に吸い込まれる。このとき、電装箱11の両側に存在する吸込口23から空気が吸い込まれるので、電装箱11で発生する熱は効率的に拡散して排熱される。
このように機械室4の吸気側に吸い込まれた空気は、蒸発器12や圧縮機14との間で熱交換され、かかる熱交換後の空気は、リアパネル15に形成された各吹出口25から機械室4の後面外部に排出されるとともに、フロントパネル9に形成された吹出口24から機械室4の前面側に一部排出される。
前記のように各吹出口25から排出された熱交換後の空気は、図1に示すように、設置部屋の壁面20にて衝突してその移動方向が変えられるとともに、設置面17と機械室4の底面18との間に存在する間隙19に沿って機械室4の前面側に向かって移動していく。
【0016】
このとき、機械室4の底部を構成するベース板6の前端面には、ショートサイクル防止板21が取り付けられているので、前記のように間隙19に沿って機械室4の前面側に移動してきた熱交換後の空気は、ショートサイクル防止板21を介して遮断される。これにより、熱交換後の空気が、フロントパネル9の各吸込口23から吸い込まれることを確実に防止することができる。
尚、フロントパネル9の吹出口24から排出された熱交換後の空気は、吹出口24に隣接する吸込口23から若干吸い込まれるが、熱交換後の空気の大部分はリアパネル15の各吹出口25から排出されるので、何等問題はない。
【0017】
次に、製氷機1が図1に示すような状態で長期間設置された場合に、その設置面の溜まるゴミ、虫の死骸当の各種の塵埃を掃除する際におけるショートサイクル防止板21の作用について説明する。
ショートサイクル防止板21は、前記したように、機械室4の底部を構成するベース板6の前端面に、2つのヒンジ22を介して略180度の範囲で前後方向へ回動可能に取り付けられている。従って、機械室4の底面18と設置面17との間に間隙19に溜まった各種の塵埃を掃除すべく間隙19にモップ等の掃除具を入れた際、掃除具がショートサイクル防止板21に当たっても、ショートサイクル防止板21は略180度の範囲で前後方向に自在に回動することができるので、機械室4の底面18と設置面17との間隙19にモップ等の掃除具を入れる箇所が限定されてしまうことはなく、また、塵埃を掃き出す箇所も限定されることはない。特に、ショートサイクル防止板21が取り付けられた機械室4の前面側から掃除具を入れることが可能となり、また、塵埃を機械室4の前面側から掃き出すことも可能となる。従って、機械室4の底面18と設置面17との間隙19に溜まった塵埃の掃除を短時間で効率良く行うことができる。
【0018】
また、前記のようにショートサイクル防止板21が回動可能に取り付けられていることから、ショートサイクル防止板21に近接するアジャスタ脚16の調整を行う際においても、ショートサイクル防止板21による制約を受けることなく簡単にアジャスタ脚16の調整を行うことができる。
更に、ショートサイクル防止板21の右端は、図3に示すように、右側のアジャスタ脚16から距離L1だけ離間するように取り付けられているので、ショートサイクル防止板21が前後方向に回動する際に、アジャスタ脚16に接触することが防止される。
また、ショートサイクル防止板21の左端は、図3に示すように、フロントパネル9に形成された3列目の吸込口23の左端から距離L2だけ離間するように取り付けられているので、リアパネル15に形成された吹出口24から排出された熱交換後の空気が、間隙19を通って機械室4の前面側まで移動してきた際に、吸込口23から吸い込まれ難くすることができる。
【0019】
尚、本発明は前記実施形態に限定されることはなく、本発明の要旨を逸脱しない範囲内で種々の改良、変形が可能であることは勿論である。例えば、図6に示すように、機械室4のベース板6に1つの吹出口25を形成し、かかる吹出口25から下方に向かって熱交換後の空気を排出する場合には、吹出口25にフィルタ(図示せず)を配設するか、又は、吹出口25に対応して、複数の排気口30を形成した底板31(図7参照)を取り付けるように構成すれば、ゴミ、虫の死骸等の塵埃が機械室4内に侵入することを防止することができる。
また、図8に示すように、吹出口25の両側にレール32を配設するとともに、各レール32に対して複数個のメッシュ33を張設したフィルタ板34を着脱可能に取り付けるように構成してもよい。かかる場合、フィルタ板34の交換等を行う際に、ショートサイクル防止板21が邪魔になることはない。
【0020】
【発明の効果】
以上説明した通り本発明に係る冷凍装置によれば、吹出口から排出された熱交換後の空気が吸込口から機械室内に吸い込まれることを防止しつつ、冷凍機本体の底部下方における設置面の掃除を容易に行うことが可能な冷凍装置を提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a suction port for sucking air from the outside into the machine room and air after heat exchange in the machine room, on both front and rear sides of the machine room of the refrigerator body in which the refrigeration unit including the compressor and the like is disposed. In particular, the present invention relates to a refrigeration apparatus having an outlet for discharging heat to the outside of the machine room, and in particular, while preventing air after heat exchange discharged from the outlet from being sucked into the machine room from the inlet, The present invention relates to a refrigeration apparatus that can easily clean an installation surface below a bottom.
[0002]
[Prior art]
Conventionally, various refrigerating apparatuses have been proposed. For example, in Patent Document 1, a refrigeration unit including a condenser and the like is disposed in a unit base in a machine room of a heat insulating box, an outside air suction port is formed in the front of the machine room, and air after heat exchange is formed in a rear portion. A refrigerating apparatus is disclosed in which an outlet is formed to blow off air, and a guard is provided below the inlet of the machine room to prevent air after heat exchange from being sucked from the inlet.
Here, as shown in FIG. 4 of Patent Document 1, the refrigeration apparatus as described above may be arranged near a wall at a corner of a room in order to effectively use the installation space. Many. In such a case, the heat-exchanged air blown out from the air outlet formed in the rear of the machine room collides with the wall of the room, changes its direction, and connects the bottom surface of the heat-insulating box and the installation surface via the pedestal. The gap formed therebetween may move to the front side and be sucked into the machine room from the suction port on the front of the machine room. At this time, the guard provided below the suction port of the machine room blocks the air flow after the heat exchange, which moves as described above, and prevents the air from being sucked into the suction port.
[0003]
[Patent Document 1]
JP-A-9-119766 (page 2, page 3, FIGS. 1 to 4)
[Problems to be solved by the invention]
In the refrigeration apparatus described above, since the guard is provided below the suction port of the machine room, the air after heat exchange blown out from the outlet at the rear of the machine room is sucked into the machine room from the suction port at the front of the machine room. Although this can be prevented, the guard is immovably fixed to the lower part of the machine room.
Here, in the refrigerating apparatus, a gap is formed between the bottom surface of the heat insulating box and the installation surface via a pedestal provided at the bottom of the heat insulating box, and is shown in FIG. As described above, if the device is installed in the corner of the room for a long time, various kinds of dust such as dust, dirt, and dead insects accumulate in the gap between the bottom surface of the heat insulating box and the installation surface. When various kinds of dust accumulate in the gap between the bottom surface of the heat insulating box and the installation surface, it is necessary to clean the dust.
[0004]
However, since the guard is fixed to the lower part of the machine room in an immovable state, when cleaning various dust accumulated in the gap between the bottom surface of the heat insulating box and the installation surface, a cleaning tool such as a mop is provided in the gap. At the same time, the place where the dust is put is limited, and the place where the dust is swept out is also limited. Particularly, it is extremely difficult to insert a cleaning tool such as a mop from the front side of the machine room to which the guard is fixed, and to sweep out dust from the front side of the machine room.

Thereby, the short cycle prevention plate 21 is stopped at the position shown by the solid line in FIG. 4 in the normal state, but when a force in the forward direction (left direction in FIG. 4) acts, two points in the direction of the arrow Y1 are generated. When it rotates to the position shown by the dashed line, and when a force in the backward direction (right direction in FIG. 4) acts, it is possible to rotate to the position shown by the two-dot chain line in the direction of arrow Y2. As described above, the short cycle prevention plate 21 is configured to be rotatable in the front-rear direction within a range of approximately 180 degrees.
[0014]
Here, the right end of the short cycle prevention plate 21 is attached so as to be separated from the right adjuster leg 16 by a distance L1 as shown in FIG. This is to prevent the short cycle prevention plate 21 from coming into contact with the adjuster legs 16 when the short cycle prevention plate 21 rotates in the front-rear direction as described above.
As shown in FIG. 3, the left end of the short cycle prevention plate 21 is attached so as to be separated from the left end of the third row of suction ports 23 formed on the front panel 9 by a distance L2. This is because, as described later, when the heat-exchanged air discharged from the air outlet 24 formed in the rear panel 15 moves to the front side of the machine room 4 through the gap 19, the third row This is for making it difficult to be sucked through the suction port 23.

At this time, since the short cycle prevention plate 21 is attached to the front end face of the base plate 6 constituting the bottom of the machine room 4, the base plate 6 moves to the front side of the machine room 4 along the gap 19 as described above. The air after the heat exchange is cut off via the short cycle prevention plate 21. Thereby, it is possible to reliably prevent the air after the heat exchange from being sucked from each suction port 23 of the front panel 9.
The heat-exchanged air discharged from the air outlet 24 of the front panel 9 is slightly sucked from the air inlet 23 adjacent to the air outlet 24, but most of the air after the heat exchange is discharged from each air outlet of the rear panel 15. There is no problem because it is discharged from 25.
[0017]
Next, when the ice making machine 1 is installed for a long time in the state as shown in FIG. 1, the action of the short cycle prevention plate 21 when cleaning various dusts such as garbage accumulated on the installation surface and insect dead bodies. Will be described.
As described above, the short cycle prevention plate 21 is attached to the front end surface of the base plate 6 constituting the bottom of the machine room 4 via two hinges 22 so as to be rotatable in the front-rear direction within a range of approximately 180 degrees. ing. Accordingly, when a cleaning tool such as a mop is inserted into the gap 19 to clean various dusts accumulated in the gap 19 between the bottom surface 18 of the machine room 4 and the installation surface 17, the cleaning tool hits the short cycle prevention plate 21. Also, since the short cycle prevention plate 21 can freely rotate in the front-rear direction within a range of approximately 180 degrees, a place where a cleaning tool such as a mop is inserted into the gap 19 between the bottom surface 18 of the machine room 4 and the installation surface 17. Is not limited, and the place where the dust is swept out is not limited. In particular, it becomes possible to insert a cleaning tool from the front side of the machine room 4 to which the short cycle prevention plate 21 is attached, and it is also possible to sweep out dust from the front side of the machine room 4. Therefore, dust collected in the gap 19 between the bottom surface 18 of the machine room 4 and the installation surface 17 can be efficiently cleaned in a short time.
[0018]
In addition, since the short cycle prevention plate 21 is rotatably mounted as described above, even when adjusting the adjuster legs 16 close to the short cycle prevention plate 21, restrictions due to the short cycle prevention plate 21 are restricted. The adjuster leg 16 can be easily adjusted without receiving it.
Further, as shown in FIG. 3, the right end of the short cycle prevention plate 21 is attached so as to be separated from the right adjuster leg 16 by the distance L1, so that when the short cycle prevention plate 21 rotates in the front-rear direction. In addition, contact with the adjuster leg 16 is prevented.
As shown in FIG. 3, the left end of the short cycle prevention plate 21 is attached at a distance L2 from the left end of the third row of suction ports 23 formed on the front panel 9, so that the rear panel 15 When the heat-exchanged air discharged from the air outlet 24 formed at the front of the machine room 4 moves through the gap 19 to the front side of the machine room 4, the air can be made hard to be sucked through the suction port 23.
[0019]
It should be noted that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention. For example, as shown in FIG. 6, when one outlet 25 is formed in the base plate 6 of the machine room 4 and the air after the heat exchange is discharged downward from the outlet 25, the outlet 25 If a filter (not shown) is disposed on the bottom plate or a bottom plate 31 (see FIG. 7) formed with a plurality of exhaust ports 30 corresponding to the air outlet 25 is attached, It is possible to prevent dust such as dead bodies from entering the machine room 4.
As shown in FIG. 8, rails 32 are provided on both sides of the air outlet 25, and a filter plate 34 having a plurality of meshes 33 stretched on each rail 32 is detachably attached. You may. In such a case, the short cycle prevention plate 21 does not hinder the replacement of the filter plate 34 or the like.
